WILLIAM W. STILWELL, OF OXFORD, WISCONSIN vLetters Patent No. 111,490,dated January 31, 1871.

IMPRoi/ EMENT iN cHunNs.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom, 'it may con-cern Be it known that I, WrLLrAM W.SrILWnLL,-ot

Oxford, in the county of Marquette and iu the State ol' \Visconsin, haveinvented certain new and useful Improvements in Ghurns and do herebydeclare thatthe following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawing and to theletters of vreference marked thereon making a part of thisspecification.

'lhe nature et' my'iuve-ntion consi/sts in the construction andarrangement of a churn, as will be hereinafter fully set forth.

In order to enable-others skilled iu the art to which'ruyinventionappertains to make and use the. same, I will now proceed todescribe itsconstruction and operation, referring to the annexed drawing, in which-Figure l is a longitudinal vertical section of my churn;

Figure 2 is a bottom view of the dasher;

Figure 3 -is a side view of the frame placed on the lid, and in whichpart of the mechanism for operating the dashers is inserted; and

Figure 4 is a view showing the mode of connecting the flasher-shaft tothe swivel.

A represents the tub, of any suitable dimensions, whiclris provided witha false bottom, B, forming a chamber, C, below this false bottom a'ndthe regular bot-tom of the tub.

lhe chamber or reservoir C is for the purpose of holding hotor coldwater, to temper the cream.

The upper orfalsc bottom B may be made 'of metal iu a practical churn,which will much facilitate a right temperature.

There is a funnel, I), attached vto the upper partof said reservoir,through which water. may be poured to press against the upper bottom.

Likewise, a, faucet, E, below, to draw off the water aft-cr the righttemperature has been acquired.

- The tub A seovcred by the lid G,a portion of which is hinged for thepurposeof erta-mining the' thermon'ieter iu rela-tion to the temperatureof the cream.

The tlicrnionieterfslides in a groove on the inside of the tub, asindicated by dotted lines at a, in 1.

. On the cover G are secured two standards, H H, the npperends of whichare cut with square tenons, Il (1.

These tenons are passed through mortises in a cross-bar, I, whichthnseonnects the two standards. Pins are then put through thc tenons 71b, securing the cross-bar I.

.it a suitable height from the cover G, on the innc1'shles it'thcstandards II H, are horizontalgrooves, in which is inserted anothercrossbar, J, and which bur is secured in place. by keys d d, moving invertical grooves on the inner sides of the standards,as shown in fig.:3.

Between the cross-bar J and the cover G, and having 4its bearings in abon` on said cover, is placed a hub, K, having beveled or miter cogs onthe outside.

This hub gears with a large imiter-wheel, L, upon theinncr end ofacrank-shaft, M, which has its bearings in suitable standards rising fromthe covei' G.

Through the hub K passes a shaft, N, which is square for a suitabledistance, and the upper end round where it has to move through the uppercrossbar I. l Y

This shaft passes downward into the tub A, and at its lower end issecured a shaft, O, of larger diameter.

On this shaft O are secured the dashers P P, which are fan-shaped, asshown in g. 2, whereby they occupy more space in the cream and force agreater quantity of air in at the same time.

' These fan-shaped dashers are arranged spirally on the shaft O, and arebeveled. downward on the flaring side for raising the cream 'wlien thedashers are in motion.

They are hollowed out ou the under side for forcing atmosphere into thecream in their vertical motion, with small orifices, i t', in the topoi' the dasher for emitting air into the cream.

The upper end of the shaft N, above the cross-bar I, passes i'nto aswivel, 7i, where it is attached by means of an iron-key, c, having anelongated slot, as shown in fig. 4. of the swivel into a groove on theshaft, which attaches the two together.

To the swivel h is hinged or pivoted a pitman, R, or crank, attached tothe wheel L, so that by the turn-y ing of the crank-shaft M the dashersobtain not only a rotating but also a vertical] y reciprocating motion.

Having thus fully described my invention,

\Vhat I claim. as new, and. desireto secure by Letters Patent, is-

1. The fan-shaped dashers I P, arranged spirally on a dashensliaf't,beveled downward on one side and hollow-'ed out on their nuclei side,with orifices t' yi through the top, all substantially as and for thepurposes herein set forth.

2. The arrangement of the shaft N, swivel h, and

yslotted key c, substantially as shown and described.

o. The combination of the tub A, )artition B,

water-reservoir C, funnel I), faucet E, fan-shaped dashers l I, and themechanism herein described for operating said dashers, when all theparts areeousti-noted and arranged substantially in the manner and forthe purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this29th day .of September, 1870.
